This invention relates to a press for forming objects and more especially to a press for straightening and rendering circular ferrules 6 Claims. (Cl. 153-48) which are placed on the ends of paper bobbins or tubes when they shall have become out of round by being run over by a truck or stepped on.

It is well known that in the textile industry tubes and bobbins are made of paper and have metallic ferrules at each end thereof. In one type of bobbin or tube the upper end of the bobbin which sits on a spindle has a ferrule which is restricted and frictionally engages the spindle on which the same is placed and therefore must be perfectly round in order to fit onto the spindle. These bobbins after being processed very often fall onto the floor and are stepped on or the wheel of a truck passes over the same which results in their being crushed to an out of round position. It is an object of this invention to provide a suitable press into which the tubes can be placed for rendering the ferrules, preferably on the base of the bobbin, perfectly circular for further use.

In bobbins of this nature, the ferrule on the lower end of the bobbin fits tightly against the exterior and interior surfaces of the base of the bobbin and does not have the rigidity of the ferrule at the top or tip end of the bobbin which extends inwardly from the inner walls of the tube or bobbin and therefore lends rigidity to the ferrule so that it is not easily crushed, but the ferrule around the base of the bobbin by fitting tightly around the inner and outer surfaces of the bobbin does not have the required metal stock therein to withstand pressure and when the wheels of a truck or the foot of an operator engages the same the bobbin is very often mashed to an out of round position and this must be brought back to a true circular position before it can be further used.

Some of the objects of the invention having h been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which Figure 1 is a top plan view of the apparatus omitting pipes for carrying compressed air;

Figure 2 is a longitudinal vertical sectional view taken substantially along the line 22 in Fig. 1;

Figure 3 is a sectional view through the control valve showing the core in one position;

Figure 4 is a sectional view through the control valve and showing the core in another position;

Figure 5 is a longitudinal sectional view similar to Figure 2 but showing a modification of the invention;

Figure 6 is an enlarged longitudinal sectional view taken along the line 6-6 in Figure 1 with the middle portion thereof broken away.

Referring more specifically to the drawings the numeral l0 indicates a suitable support such as a table for supporting the apparatus. A base member I l is suitably secured by means shown in Figures 1 and 2 to the support In which base member II has adjustably mounted thereon a dovetailed member l2 which is secured in position by means of bolts l3. The member l2 has a bore l4 therein in which is adjustably mounted a pilot member l5 having a projection l6 forming a circular groove I1 and which acts as a pilot for one end of the tube to be presently described. The pilot member I5 is secured in position in the member I2 by means of a set screw I8.

The base member II has integral therewith a barrel portion having a bore 2| therein in which is slidably mounted a tubular member 22 which has a bore 23 extending longitudinally thereof and this bore 23 is flared outwardly as at 24 at its right hand end in Figure 2. The open end of the bore 2| is closed by an annular plate 25 secured in position by any suitable means such as screws 26. Between the 'slidable die member 22 and a restricted portion 21 of the bore 2| is a compression spring 28. The barrel member 20 also has a bore of slightly smaller diameter than the bore 2| and which communicates with the restricted portion 21. The restricted portion 21 has a bearing ring 33 therein and slidably mounted in the bearing ring 33 is an enlarged portion 35 of a plunger 36 which has a tapered portion 31 adapted to enter the end of the tube T.

The tube T has a ferrule 49 around its base portion (Figure 2) and another ferrule 4! around its tip portion. The ferrule 4! extends inwardly a substantial distance from the inner surface of the tube T and turns inwardly to provide a restricted bore B for fitting around the tip portion of a spindle.

' The die member 22 is restricted at its outer end where it passes through the annular plate 25 thus providing a shoulder 46 for limiting outward movement of the member 22 under pressure of the compression spring 28. The bore 30 is open at its right-hand end and the barrel portion 20 is provided with a flange to which is secured by bolts 41 a flanged portion 48 of an annular member which is threaded to receive one end of acylinder 50 in which is mounted a piston 5| penetrated by a piston rod- 52 which is integral with the portion 35. The piston rod 5| is slidably. mounted in a bearingring 49 mountedin the annular member 48. The piston is secured on the piston rod 52 by any suitable means such as the right-hand end of the rod 52 being threaded and receiving a nut 54.

At the right-hand end of the cylinder 50 isa closure plate 60 which has an annular rib GI threaded interiorly for receiving the right-hand end of the cylinder 50. The closure plate 60 has suitable holes 62 therethrough for securing the same to the support 10. The closure plate 60 has a bore 64 through which communicates with a bore 65 in a closure plate 66 secured to the plate 60 by any suitable means such as bolts-6T. The

member 48 has a bore 10 therethrough which communicates with the left-hand end of the cylinder 50 and secured in this bore is a pipe H which leads to one of the ports of a valve housing 12 having a core 13 therein provided with passageways M and 15. The valve core 13' is fixed on a shaft 16 which extends to the outside of the ,valve housing 12 andhas-an operat ng handle Ill fixed thereon. The valve housing 12- also has a second port to'w-hich a pipe 80 is secured and this pipe Sllextends to and is threadably secured in bore 65 of plate 66. The valve housing 12 also has a pipe 82leading from a third port which pipe 82 is a supply pipe and leads to a suitable source of compressed air such as a tank-'85. The

valve housing, 12 also has an exhaust port 86 through which air-is. exhausted in the" operation of the machina;

In operation tube T isinserted into the-flared .outcavity 24v and pressure is applied toward'the right in Figures land-2 which willcompress the compression spring- 28; andallow the tipend of the tube to be fitted overthe projection l6 and rest in position shown bestin Figure 6. The pressure of spring? 28- will holdit in-this position and then-the valve port l3;-will beturned to the position shown in Figure; 3 which will allow compressed air to pass through passageway 15 and pipe 80to the right-hand end of the cylinder 59 which force the piston M to the left in Figure 2 and which wil deliver an impact to the. tapered portion 3! tocause it to fit intothe rightehand end of the tube T or'the position shown in- Fig ure 6 which will restore the right-hand; end of the tube T to circular position.

Then the. valve core 13 is switched to theposition shown in Figure 4rwhich will allow the air to exhaust from the right-hand end'of the cylinder 58 through the passagewayv l5: and eX- haust port 86 and at the same time will allow com.- pressed air to flow throughpassageway Minto the left-hand end of cylinder 50 which will'withdraw the piston and the tapered portion 31' of the plunger to the right as shown in Figure 2 but,

'of course, continuedpressure will force the right,-

hand end of the piston rod 52 to the right-hand end of the cylinder and againstthe plate 60.

In this position the tube T may be. withdrawn from the apparatus and a new tube inserted;

In Figure 5 a slightly modified form of the invention is shown-and the left-hand end ofthe invention being identical to that shown in Figures 1 and 2 will'bear the same reference characters.

The structure shown ii -Figure; 5'is operated by hand or foot power or manually instead of by compressed air or other compressed fluid as shown in Figures 1 and2 In this formof the invention, the base plate: I l is shown as being secured to a suitablesupportlfl by bolts- I Ill). The base plate H has a slightly modified portion I0! integral therewith differing from theportion in the previously-described form-of the invention. This portion It! has a bore I02 or the same size as the bore 2| in which the member 22 is mounted and a compression spring 28 identical to that shown in Figure 2 is disposed around the enlarged portion 35 and extending from this portion 35 is a piston I04 which has a piston lilii thereon. The enlarged portion 35 extends through a bearing l0! before it is reduced in diameter to form the piston rod I64. The compression spring 28 serves the same purpose, that is to move the annular die member 22 toward the left in both Figures 2 and 5. The piston 195 instead of being propelled by air pressure is propelled by a compression spring Hi3 which is disposed in a bore I89 which bore also accommodates the piston rod Hi l. The right-hand end of the portion lBl is flared as at H l and a closure plate H2 is secured thereon by any suitable means such as bolts I I3.

The base portion H in the modified form has a downwardly projecting ear H5 extending through an opening H5 in the support l0 and has pivoted thereto on a pivot lit a bell'crank C having a lower arm Ill and an upper arm HS. On the-upper. arm H8 is pivoted as at H9 a dog which is held against a projection l2] extending from the arm H8 by means of a tension; spring I23 secured to the upper portion of the dog atone end and to the outer end of the arm ill as at'l24l Pivoted to the outer end of the arm ill, as at 126, is a link I21 which extends downwardly and is pivoted-as at 30 to a foot lever 53! which foot lever is normally held in solid line position by means of a tension spring 132. This foot lever IN is pivoted, as at 33 on a stand i3 1 rising from a, suitable support such as a. floor #35 of a building. The left-hand end of the foot lever l3l has a pedal portion (35 so that an operator can step upon the pedal i36 to move the bell crank C in a clockwise manner in Figure 5 which will compress the compression spring. W3 and retract the tapered portion 3T from the solid line position shown in Figure 5 to the dotted line positionor until'the upper-end of the dog 12D passes by the piston Hi5 which will cause the spring then suddenly to force the piston 1&5 and associated parts quickl to the left in Figure 5 which will drive the tapered portion into the nearest end of the tube T or to the solid: line position shown in Figures 5 and 6 to thus deliver an impact: to; straighten out and render circular the'ferrule 40' on the base of the tube T;
